Chalk Crayon Under an SEM Scanning Electron Microscope

ASPEX, a company that makes desktop scanning electron microscopes (SEMs), is running a promotional campaign under which anyone can mail them a sample, which they will then image under one of their SEMs. The results will be posted on their webpage, and all for free! Challenge: Take advantage of their offer to produce publishable data! [via Boing Boing]
